I've installed Notepage Pro onto our new Windows 2012 R2 server but am having a bit of a problem at the moment. It's complaining about an OCX file not being found:

29/06/2015 10:57:07 Dialer Started
29/06/2015 10:57:08 Program Halted. Error# 339 Component 'MSCOMM32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid in Procedure: main

I've followed the Win7 64bit install steps and it's installed in the c:\NotePager Pro folder.
I've tried running 'regsvr32 mscomm32.ocx' but it complains that the module fails to load.

Hm... this may be due to the NotePager Pro version 3 engine not being able to make the COM call properly. We have a beta of the next release of NotePager Pro that should be able to access the device and if you're interested, please email support at notepage dot com so we can start the process of registering you as a beta user.

NotePager Pro was only ever programmed to run as an application. If you need something that can run as a Windows service, I would definitely recommend our other program, PageGate. PageGate is our server based solution that can run as a Windows service and also has far, far more robust support for cellular modems than NotePager Pro does.
